Based on the evaluation of dynamic performance for feed drives in machine tools,this paper presents a two-stage tuning method of servo parameters.In the first stage,the evaluation of dynamic performance,parameter tuning and optimization on a mechatronic integrated system simulation platform of feed drives are performed.As a result,a servo parameter combination is acquired.In the second stage,the servo parameter combination from the first stage is set and tuned further in a real machine tool whose dynamic performance is measured and evaluated using the cross grid encoder developed by Heidenhain GmbH.A case study shows that this method simplifies the test process effectively and results in a good dynamic performance in a real machine tool.
